tically, and also the reciprocating device. The'lifting-bar is not shown in this figure, and Fig. 9 shows a modified construction of the device for moving the pile-warps trans-- versely across the pile-wires.

In the accompanying drawings, 1 is a portion of a loom side or frame. 2 is the breastbeam; 3, the'take-up roll forthe woven fabric 3, and 4 the lay-sword; 5, the lay; 6, the

hand-rail, and 7 the reed. In this instance there are three harness-frames 8, 9, and 10,

' provided with heddles 8, 9, and 10, which (See Fig. 1.) The lower ends ofthe heddles 14 preferably extend loosely through openings in a transverse bar 20, which is secured at its ends to stands 21 on the loom-frame 1 and have attached thereto by cords 22 weights 23.

Each heddle 14, which is preferably made of flat metal, has a bend or offset 14 therein near its central longitudinal portion, and the bends or offsets 14 are so arranged relatively to each other as'to form open or clear spaces on each side of the upper end of each blade 24, which ispreferably made separate from and secured at its lower end to the heddle 14 and has secured to its upper end, which is preferably bent over to form a loop, the inner' end of the pile-wire 15. (See Fig. 7.) The blades 24 are preferably of two different lengths. The shorterones extend at their upper ends in one horizontal plane, and .the longer ones extend in another horizontal plane, forming two sets or series with the long and short blades arranged alternately.

The pile-wires 15 are preferaby made of flat metal, tapering toward their free ends,

- and may be pivotally connected with the upper ends of the blades 24. In this instance they extend into theloops 24 and are secured therein by pivot-pins 26 to have a pivotal motion in a vertical plane, as shown'by broken lines in Fig. 7. The extreme pointed end 15 of, each pile-wire 15 may be made separate from andpivote'd to the main-portion of the wire at 15 to have an independent vertical movement. (See Fig. 7.) I

Instead of making the pile-wires 15 of fiat metal, as shown in Fig. 7, they may be made of round flexible wire, as shown at 15 in Fig. 8, and pivotally attached to the upper ends of the blades 24.

By reasonpf the upper ends of the blades 24 extending in two dilferent planes the attached ends of the pile-wires 1-5 will also extendjn two different planes one above the other. The advantage of this is thatthere is more space for the pile-warps to work in, and they will not be liable to catch on the.

upper ends of the blades 24 or pass down on the wrong side of said blades.

To carry the pile-warps over the pile-wires 15 first on one side and then on the other in' the formation of the loops, I preferably use a reciprocating comb 27, having a transverse motion in the direction ot the width of the fabric and supported in proper position just back of the heddles 14, in this instance on crank-arms 28 and 29,'which are, fast on ver-, tically-extending and rocking shafts 30'and 31, having hearings in stands 32 and 21. To one of the rock-shafts, as 30, is secured a crank-arm 33, to which through intermediate connections (not shown) to some driven part ofthe loom is communicated a movement 'at regular intervals to rock or rotate the shaft 30 and communicate at regular intervals a transverse reciprocating movement to the comb 27, between the teeth 2770f which the pile-warps 34 are carried up at the proper time and carried over the adjoining pilewires by the transverse movement of said comb 27. The lowerends of the teeth 27 of the comb 27 extend down a little below the upper ends of the lower series of blades 24.

Instead of thecomb device above described and shown in the drawings any other suitable device for moving the pile-warps transversely over the pile-wires to form the loopsv may be .employed'for example, the device shown in Fig. 9, which consists of a series of levers 50, pivoted at 51 on a stationary bar 52, with their lowerends extending down below the upper ends of the blades 24and their upper ends pivoted toa transversely-moving bar 53, having a reciprocating movement corresponding to the movement of the comb 27.

In connection with myimprovements above described I preferably use mechanism connected with the cords or heddles of are pilewarps and means for operating said mechanism at regular intervals or after a cei tain number of picks of filling to cause all of the pile-warps which are in the upper or lower plane of the shed to be raised-or carried up above the upper ends of the blades to which are attached the pile-wires. In this instance I have shown in the drawings a verticallymoving bar 35, having a series of holes there -in through which extend the cords 36, which form the heddleq-cords for the pile-warps 34. Said cords have weights 36 on their-tower ends and have knots therein to engage the vertically-moving bar 35. A vertical motion ,is communicated to the bar 35 to raise said bar to its highest position and with it all of the cords 36, carrying the'pile-warps at regn-' lar intervals, in this instance by means of chains 38 and links 39, connected to crank{ arms 40 on the rock-shaft 41, supported in bearings 42 on the upper endsof the loom- 'frame 1. On one end of the rock-shaft is fast a crank-arm 43, to'which is secured the upp'erend of the connector The lower driven from some driven part of the loom.

The ends of the vertically-moving bar 35 in this instance are provided with plates 35,

which extend into a vertical slot in the stand 19, secured to the loom-frame -1. -In the forrotation of the sheds in the operation of weaving .when the lifting-bar 35 is in its lowest position the pile-warps 34 connected therewith are carried to the lower, plane of the shed, as shown in Fig. 4, preparatory to the throwing of the shuttle and the beating up of the lay. When the lifting-bar is in its intermediate or middle position, the pile-warps 34 are carried to the upper plane of the shed, asshown in Fig. 3, preparatory to the throw ingof the shuttle and the beating up of thelay.' When the lifting-bar is carried to its highest position, asshown in Fig. 2, then the and movement of the pile warps 34 are carried up between the teeth 27 of the comb 27, as shown in Fig. .2, so

that the transverse movement'of the comb will carry all of the pile-warps-in one direction or the other over the pile-wires, according to the direction of movement of the comb. The raising of the lifting-bar 35'atregular intervals to its highest position will carry up all'of the pile-warps 34 above the upperends of the blades 24 and between the teeth of the comb 27 and will insure the proper position v pile-warps in the'fo-rmation of the shed.. 7

In Fig. Sis shown a modified construction of-the bar 17, which carries the heddles, to which are attached the blades and the pilewi'res. In said figure the transverse bar 17, which supports the heddles 14, has a reciproeating vertical motion to carry the attached ends of the wires 15, preferably made of flexible wire, above and below thehorizontal plane of the woven fabric, as shown by full and broken lines in said figure. The transverselymoving comb 27 also has a corresponding re- "ciprocating vertical motion, as shown by full r In the drawings I have shown the several parts of the loom adapted for plain weaving and only one set of pile-warps 34, all of which arecorinected to the vertically-moving lift- -ing-bar 35, to be raised and lowered by said baratthe proper time and carried into ongagement with the transverse reciprocating -comb 27 or other device to be carried over the pile-wiresl5-to form the pile-loops; but in jcase of figured pile-fabric weaving there will betwo or more sets of pile-warps, and all-the of the shed to the upper plane'willcarry with it to the upper plane all the pile-warps which have not been called and raised by the jacquard, and the further raising of the liftingbar 35 to its highest position will carry with it above the upper ends of the blades 24, carrying the pile-wires 15, all the pile-warps which have not been'called and raised by the jacquard into engagement with the teeth 27 on the comb 27 to be carried over the pile- -wi res to form the -pile-loopsthat is, at regular intervals or after a certain number ofpicks, preferably at every fourth pick, all the pilewarps which are not raised by the jacquard to their highest position are raised by. the, liftingbar 35v or equivalent mechanism to their highest position or above the upper ends of the blades 24, carryingthe pile-wires 15.

I

The lifting-bar 35 or equivalent mechanism is particularly intended to be used in connection with two or more sets of pile-warps operated from a jacquard.

It will be understood that the details of' construction of my-improvements may be va- '.r ied, if desired.
